Hi all.I'm on Stretch, (9.2.1), having bumblebee-nvidia installed (laptop with GeForce 840M).I hibernated my laptop and then when powered on, the mouse cursor rendering became super weird.Description of the weird things happening, as I can't really explain otherwise:* Sometimes I have a trail of half pointers following my mouse* When right clicking, the pointer covers a square part of the first option in the menu* Sometimes I get a lot of pointers just blinking in random places on the screen and my pointer dissapears

When clicking, it registers the click in the right place.Also, taking a screenshot for example cleans all the problems until I move the mouse again.I'm guessing it's something with the rendering as functionality is ok.About the connection to hibernate - I'm not sure but it didn't happen before.
